Application filed December 1'7, 1928., Serial No. 681,300.

The invention relates to machines for formin channels and particularly window glass channels consisting of an outer strip and an inner strip within the outer strip.

The invention has for one of its objects the provision of a machine which, during the advancement of a pair of metallic strips, fashions the same and also nests one strip within the other. Another object is to provide a machine which also secures the strips to each other duringtheiradvancement. A further object is the provision of means which operates intermittently to secure the strips to each other.

\Vith these as well as other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

Fig. 18 is a side elevationjpartly in section, of a portion of the window glass channel formed in the machine.

ln general, the machine for forming the window glass channel comprises a series of sets of driven rolls which advance a pair of flat metallic' strips or ribbons, and during their advancement fashion the same, nest one within the other, and secure the same to each other. The machine comprises the sets of rolls 1, 2, 3, 4, 5,6, and 7 all of which are 0 driven in timed relation to each other through the series of intermeshing gears 8 extending longitudinally of the machine and at one side thereof.

The sets of rolls 1, 2, 3 and 4 each com prise two pairs of cooperating upper and lower rolls, corresponding pairs of which successively operate upon metallic strips 9 and 10 whlch are advanced from reels in advance of the machine. The set of rolls 1 com rises the pair of upper and lowercoopcrating rolls 11 and 12 and the pair of upper and lower cooperating rolls 13and 14, the first pal-r operating upon the flat metallic strip 9, and the second pair operating upon the flat metallic strip 10. The, first pair ,of rolls changes the contour of thestrip 9 by formmg the longitudinally extending. beads 15 near its middle'portion and by upturning the edge portions 16. The portion 17 of the strip intermediate the beads 15 forms the base ofthe completed strip. The second pair of rolls 13 and 14 operate upon the strip 10 to form portions diverging upwardly from its middle. V Y

The set of rolls 2 comprises the pair of upper and lower cooperating rolls 18 and 19 which operate upon the strip 9 after it has left the pair of cooperating rolls 11 and 12 to concave the same upwardly and at the same time to return-bend the edge portions 16. This second set of rolls 2 also comprises I the pair of upper and lower cooperating rolls 20 and 21 for operating upon the strip 10 after leaving the first air of rolls 13 and 14. The rolls 20 and 21 end the strip to form the downwardly extending portion 22 and the laterally and downwardly inclined portion 23, the portion 22 forming the base of the completed strip.

The set of rolls 3 comprises the pairs of upper and lower cooperating rolls 24 and 25 which operate upon the strip 9 after leaving the set of rolls 18 and 19 to bend the portions of the strip outside of the beads 15 still further upwardly and at the same time to bend the flanged edges 16 still further downwardly. The set of rolls 3 also comprises the pair of upper and lower cooperating rolls 26 and 27 which operate upon the strip 10 after it leaves the pair of rolls 20 and 21 and bend the lateral downwardly inclined portion 23 of the strip downwardly to a greater'extent.

The set of rolls upper and lower cooperating rolls 28 and 29 which operate upon the strip 9 after leaving the pair of rolls 24 and 25 and bend the portions of the strip outside of the beads 15 further upwardly. This set also comprises loo 4 comprises the pair of I within the strip 9 with its base 22 adjacent to and above the base 17 of the strip 9. 33 is a mandrel for guiding the strips 9 and with the bases of the strips adjacent to and below the mandrel. The strip 9 embraces the mandrel while the notched portion 23 of the strip 10 slidably engages in the inclined slot34 extending longitudinally of the mandrel while the strips are passing at the same rate along the mandrel. The bases 22 and 17 thereof have tongues 35 and 36 struck upwardly therefrom by means of the shearing roll 37 which forms a part of the set of rolls 5. Upon continued advancement of the strips, the struck-up tongues 35 and 36 are bent back upon the bases of the strips by means of the shoulder 38 in rear of the set of rolls 5 and forming the rear end of the slot 39 extendin longitudinally at the bottom of the mandrel 33. This slot is necessary to permit of striking the tongues upwardly from the base of the strips. To crimp the tongues 35 and 36 u on the bases of the strips I have provide the roll 40 mounted in the yoke 41 below the bases of the strips and held tightly thereagainst by means of the set screw 42 engagin the top of the yoke and abutting against t e top of the mandrel 33.

Upon leaving the mandrel, the strips pass successively through the sets of rolls 6 and 7 comprising respectively the pair of coopcrating upper and lower rolls 43 and 44 and the pair of cooperating upper and lower rolls 45 and 46 which operate upon both the strips 9 and 10 to fashion the same to the desired final form.

The mandrel 33 is held in place by means of the block 47 in advance of the set of rolls 5 and preferably integral with the mandrel,

this block being bolted to the table 48 above the bed plate 49 of the machine. To hold the mandrel from rotation, I have provided the upwardly and rearwardly extending arm 50 secured to the block 47 and engaging in the annular groove formed in the upper roll 51 of the set of rolls 5, this groove permitting of the passage of the mandrel 33 between itself and the lower roll of the set.

It is essential that the tongues 35. and 36 struck upwardly from the bases of the strips 9 and 10 respectively be so located that the' openings in the bases formed by striking up the tongues register with the notches 32 in the lateral inclined portion 23 of the strip 10 so that means for securing the completed window glass channel to the frame may be readil inserted through the "notches 32 and ext'en through the openings in the bases. The strikin -up of the tongues is accomplished by s earing )rojections or teeth 52 upon the shearing rol 37 and equally spaced about its periphery, and the controlling of: the operation of the shearing roll is accomplished by mechanism operated by the advancement of the strips. As shown articularly in Fig. 7, the shearing roll 371s frictionally driven, it being located between the sections 53 and 54 forming the lower roll of the set of rolls 5. 55 is a driving member formed of suitable material such as leather which is held against one side of the shearing roll 37 by means of the set screw 56 threaded in the section 54. To hold the shearing roll 37 from rotation, I have provided the yoke 57 pivotally mounted upon the table 48 and having the depending projection 58 engageable with a'shearing projection or tooth 52. This yoke embraces the mandrel 33-and is yieldably held so that its depending projection 58 will be in the path of the shearing projection or tooth by means of the coil sprmg .59 connected to the upper end of the yoke and to the table 48. To actuate the yoke 57 and release the shearing roll 37, I have rovided the release member 60 which slidagly engages in a longitudinally extending slot 61 in the top of the mandrel and has a stem 62-slidably engaging in the block 47. This release member is provided with the depending projection 63 which is adapted to engage in the notches 32 by gravity so that upon the advancement of'the strips the release member will also be advanced. The advancement of the release member is continued until its rear end has engaged the yoke 57 to swing the same until its depending projection 58 becomes disengaged from the, shearing projection or tooth 52. Then the depending projection 63 of the release member is disengaged from the notch in the strip 10 by means of the cam 64 upon the mandrel which is engaged by the inclined face 65 upon the release memher. The location of the parts is such and the rate of rotation of the shearing roll and rate of advancement of the strips also is such that when the shearing roll has been released, one of its shearing projections or teeth will strike up the tongues in the bases of the'strips so that the opening formed by striking-upthe tongues will register with a notch in the strip 10. Upon disengagement of the release member 60 from the strip 10, the yoke 57 is returned by the coil spring 59 to its normal position with its depending projection 58 adapted to engage the succeeding shearing projection or tooth 58 of the shearing roll 37. This yoke returns the release member to its normal position disengaging the same from the cam 64 and allow- Hit! ing it depending projection 63 to drop into the succeeding notch 32 of the st ip 10, after which the same cycle of operations is repeated. I

While I have used the term channel throughout the description, the mvention in its broader aspects is not limited to a machine for forming an article having a strlp of true channel cross section, but applies to a machine for forming a shape or molding having nested strips neither of which are necessarily of true channel cross section.
